Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
92 words
A prosthesis for use in joining hollow organ parts or systems, said prosthesis comprising a fragmentable body defining outer organ-supporting surface parts thereon adapted to be arranged in abutting relationship with inner surface parts of the organs to be joined, said body having a compressive strength sufficiently low to allow fragmentation of the body by application of a pressure to the outer surface of the tubular organs subsequently to the anastomosing of the same, said pressure being below a pressure causing any substantial lesion of the tissue of the tubular organ parts.
Claim 2
Dependent Claim
92 words
A prosthesis for use in joining hollow organ parts or systems, said prosthesis comprising a fragmentable body defining outer organ-supporting surface parts thereon adapted to be arranged in abutting relationship with inner surface parts of the organs to be joined, said body having a compressive strength sufficiently low to allow fragmentation of the body by application of a pressure to the outer surface of the tubular organs subsequently to the anastomosing of the same, said pressure being below a pressure causing any substantial lesion of the tissue of the tubular organ parts.
Claim 3
Dependent Claim
42 words
A prosthesis as claimed in claim 1 the body of which comprises one or more degradable and/or erodable and/or water-soluble, essentially non-toxic materials which are solid at a temperature of 40°C or higher, preferably 50°C or higher, more preferably 60°C or higher.
Claim 4
Dependent Claim
69 words
A prosthesis as claimed in claim 2 in which the materials are selected from the group consisting of hard paraffin; beeswax; ceresin; higher fatty alcohols such as cetyl, stearyl, cetostearyl alcohol or the like; cholesterol; japan wax; kokkum butter; lard; microcrystalline wax; fractionated palm kernel oil; spermaceti; cetyl esters wax; squalane; wool alcohols; wool fat; carnauba wax; polyglycols; theobroma oil; chocolate; macrogol ethers; glycerol ethers; glycol ethers; and poloxamers.
Claim 5
Dependent Claim
14 words
A prosthesis as claimed in claim 3 in which the material is a polyglycol.
Claim 6
Dependent Claim
36 words
A prosthesis as claimed in claim 4 in which the material is polyethylene glycol, preferably with an average molecular weight in the range from 10,000 to 35,000, in particular from 15,000 to 30,000, especially about 20,000.
Claim 7
Dependent Claim
15 words
A prosthesis as claimed in any of the previous claims having a substantially circular cross-section.
Claim 8
Dependent Claim
32 words
A prosthesis as claimed in any of the previous claims in which the ratio between the length and the largest diameter of the prosthesis is in the range from 2:1 to 7:1.
Claim 9
Dependent Claim
27 words
A prosthesis as claimed in any of the previous claims in which the body comprises end portions the supporting surface parts and a narrowed intermediate portion therebetween.
Claim 10
Dependent Claim
17 words
A prosthesis as defined in any of the previous claims having end portions with tapered outer ends.
Claim 11
Dependent Claim
18 words
A prosthesis as defined in any of the previous claims in which the body defines an inner cavity.
Claim 12
Dependent Claim
10 words
A prosthesis as defined in claim 10 having closed ends.
Claim 13
Dependent Claim
10 words
A prosthesis as defined in claim 10 having open ends.
Claim 14
Dependent Claim
39 words
A prosthesis as defined in any of the previous claims which further comprises at least one thread-like fixation means having one end connected to the intermediate portion of the body for temporarily fixing the organ parts to the prosthesis.
Claim 15
Independent Claim
55 words
A method for joining hollow organ parts or systems, said method comprising 1) inserting a prosthesis according to any of claims 1-13 into and between the organs to be joined; 2) joining the two organ parts by anastomosis; and 3) fragmenting the prosthesis by application of pressure to be outer surface of the tubular organs.
